Amplifier: Description and Operation
AMPLIFIER
DESCRIPTION
Vehicles equipped with the Boston Acoustics speaker package have a separate amplifier unit. The amplifier is rated at 288 watts. The amplifier is
mounted to the left rear quarter panel behind the quarter trim panel.
OPERATION
The amplifier receives fused battery current from a fuse in the Integrated Power Module (IPM) at all times. The internal circuitry of the amplifier
switches the amplifier on based upon a CAN bus message that is received from the radio receiver whenever the radio is turned on. The amplifier receives
the sound signal inputs from the left and right rear outputs of the radio, then sends the amplified speaker outputs for each of those channels to the
speakers.
